Title: Improvements in or relating to a process for producing silicon steel
Inventor: CREDE JOHN HARRIS
IPC: C21D8/12
Filed: 1958-06-24
Abstract: A process for producing highly grain oriented silicon steel for magnetic purposes comprises heating a silicon steel ingot containing 2.5% to 4% silicon to a temperature above 2300 DEG F., e.g. between 2300 DEG F. and 2475 DEG F. hot working the heated ingot into hot rolled strip of 0.060 to 0.10 inch in thickness before the temperature drops below 1600 DEG F., the hot working from heated ingot to hot rolled strip being a direct hot working without an intermediate reheating of the steel, and thereafter subjecting said hot rolled strip to one or more cold rolling treatments and a final high temperature box anneal.  The steel strip may be subjected to an intermediate anneal subsequent to the cold rolling consisting of an open anneal between 1600 DEG F. and 1850 DEG F.  A second cold rolling step may be followed by a decarburizing anneal between 1400 DEG F. and 1550 DEG F. including the open anneal.  The final box anneal takes place in dry hydrogen between 2100 DEG F. and 2200 DEG F. A silicon steel so treated has a composition within the following percentage ranges by weight:-Si 2.9-3.4; C 0.02-0.035; Mn 0.035-0.1; P 0.05-0.02; S 0.05-0.025; Ni 0.03-0.15; Al 0.05 max.; Cu 0.05-0.3; Sn 0.005-0.02; Fe balance.  An alloy disclosed having the above composition also includes Co 0.011%. Specification 442,211 and U.S.A. Specification 2,599,340 are referred to.

Filed: 1967-05-05
Abstract: 1,150,676. Filling bags. O. HOFLIGER and R. KARG, [trading as HOFLIGER & KARG]. 5 May, 1967 [17 May, 1966], No. 20903/67. Heading B8C. A closed and filled bag is lifted by its upper edge between a pair of sealing jaws until the contents of the bag bear against the underside of the jaws, whereupon the jaws effect a seal. An air escape passage is provided in the bag at the station where the bag was filled and closed. In the form described, the bag is lifted by jaws 12, 13, Fig. 3 carried upon a pivotable arm 8. When the bag 1 is located upon platform 24, the arm 8 pivots downwards and the jaws grip the top of the bag. As the arm moves upwardly, welding jaws 25 move together and effect the seal when the filling material lays against their underside. A knife 29 then severs the bag from jaws 12, 13. The jaws are opened and closed from a reciprocating cam 18. The resultant seam may be folded and pressed against the side of the bag by a heated punch. At the prior filling station, the bag is sealed along its upper edge and the top of the bag wall is slit to provide an air escape passage. Alternatively this may be achieved by having an incomplete upper edge seal. The bag is vibrated during its passage from the filling station to the lifting and final sealing station.

Abstract: 1,171,123. Laminated films. W. R. GRACE & CO. 10 May, 1967 [11 May, 1966], No. 20976/66. Headings B5B and B5N. [Also in Division B8] A film, usable for shrink packaging, is formed from an orientated laminate of a vinyl chloride polymer or copolymer and an ethylene polymer or copolymer. The laminates may be prepared by bonding together pre-formed films with an adhesive or by extruding a coating of the ethylene polymer on to a preformed film of the vinyl chloride polymer. Alternatively, a tubular laminate may be produced by extruding two or three layers through concentric tubes. The laminate may be orientated in the longitudinal direction by passing through heated rolls, running at different speeds, and transverse orientation is effected through sets of clamps moving in divergent paths, which grip opposed edges of the laminate. The tubular laminate is orientated by inflation with air. In one example a P.V.C. film is treated with a corona discharge before the application of a coating of polyethylene. Examples of suitable polymers are given.

A rotating matrix - type thermal regenerator comprises a rotating drum 18 containing heat regenerative material 40 forming a plurality of passages 38 extending parallel to the axis of rotation, two end baffles 22, 24 in peripheral sealing contact with the ends of said drum baffle 22 being stationary and baffle 24 being supported on cradle 110 (Fig. 7), to be movable in the direction of the longitudinal axis of the drum while still being kept in sealing contact with the drum (as for example by springs 120) as the drum expands and contracts during the heat exchange process. Referring to Fig. 1, combustion air for a furnace 14 enters baffle 24 at inlet 124 and is heated in the drum, passing into the furnace through outlet 82. Exhaust gases from the furnace pass into the drum at inlet 84, give up their heat to the regenerative material and leave at outlet 126 to the stack 25. The drum is rotated on rollers 52, Fig. 3, driven by motor 56, Fig. 1. To prevent exhaust gases trapped in passages 38 contaminating the combustion air, purging nozzles 142 are positioned in a central dividing wall 128 of stack-end baffle 24 and compressed air blows the exhaust gases down the passages and into inlet 84 of the furnace-end baffle 22 via L-shaped receiving passages 98, Fig. 8 (not shown). Similarly heated combustion air trapped in passages 38 is blown back into inlet 124 via receiving passages 142, Fig. 7. The rubbing seals 108 between the end baffles and the drum are made of asbestos, Fig. 3. The matrix drum comprises a steel shell 26 lined with heat-insulating material 28 and containing fire bricks 40 shaped and stacked to provide the passages 38, the bricks being cemented together and supported by an outer refractory cement lining 44. The centre passages which are not utilized for heat exchange are sealed off at their ends with plugs 42.

Abstract: 916,372. Plating strip electrolytically. STAHLUND WALZWERKE RASSELSTEIN/ANDERNACH A.G. June 15, 1960 [June 20, 1959], No. 21052/60. Class 41. Metal strip (e.g. steel) is coated electrolytically with metal (e.g. tin) and the coating is melted and thereafter solidified by quenching with a jet or stream of liquid which extends over the full width of the strip. As shown, coated strip 2 issuing from plant 1 in which the coating is melted, passes tube 3 having slot-like opening 3a from which jet 4a of quenching liquid 4 impinges on the strip at an acute angle α to the direction of travel A of the strip. Quenching may alternatively be effected using a stream of liquid derived from the overflow of a trough (Fig. 2, not shown). The side of the strip which is contacted with the quenching liquid is given a matt appearance which thus serves to mark a side in cases where the strip has coatings on the two sides of different thicknesses. If both sides of the strip are to be quenched, two quenching devices are provided, one on each side.

Filed: 1919-08-27
Abstract: 142,005. Lane, H. M. Aug. 27, 1919. Drying-ovens.-Relates to a method of drying cores and consists in placing the cores in an oven, passing heated gases into the oven and around the cores, allowing the gases to escape freely at the bottom of the oven, and collecting the saturated gases in a chamber beneath the oven from which they are withdrawn by a stack. The cores are placed on racks or shelves in an oven 1, and the products of combustion from a firebox 21 are introduced into the oven by a flue 6 controlled by a damper 7. Additional air may be introduced beneath the firebox and into a connecting flue 25 by means of a fan 31. The floor of the oven is constructed of perforated plates 9, and a collecting chamber 10 is arranged beneath the floor. Thus the gases from the flues. after passing over the cores and becoming cooled and saturated with moisture, pass through the floor into the chamber 10 where they are exhausted through a flue 14 leading to the stack 32. In order to produce a draught, the stack 32, Fig. 7, is perforated over part of its length, and the perforated portion 37 is surrounded by an air chamber 34 connected with the fan 31, Fig. 5. A tapered pipe 38, Fig. 7, is placed within the stack and forms a nozzle. The air blast from the fan, passing through the perforations 37, is deflected upwards by the pipe 38 and produces a suction at the base of the stack.

Title: Improvements in or relating to the treatment of films, threads, fabrics and like materials made from or containing cellulose esters and ethers
IPC: D06M15/05
Filed: 1928-07-24
Abstract: 323,521. Dreyfus, H. July 24, 1928. Drawings to Specification. Yarns, treating with liquids.-Artificial filaments, threads, and the like composed of organic substitution derivatives of cellulose for example, organic acid esters of cellulose or cellulose ethers, or mixed threads and the like containing such artificial filaments or threads, are impregnated with cellulose by treating them with a solution of cellulose or of a celluose compound which is subsequenty decomposed to cellulose. The materials may, for example, be treated with solutions of cellulose, for instance in aqueous thiocyanates, such as calcium or ammonium thiocyanates, or in zinc chloride or ammoniacal copper solutions and then subjected to any suitable treatment, for example with water or dilute acids, in order to precipitate the cellulose. Alternatively, the materials may be treated with solutions of viscose and then with solutions of acids, acid salts or other substances to precipitate cellulose or they may be treated with a solution of nitrocellulose in a non-solvent for the organic substitution derivative of cellulose, for example in ether-alcohol solution, and thereafter subjected to saponification, for example with aqueous solutions of alkalies, or denitration, for example with dilute ammoniacal solutions of sulphydrates, such as commercial ammonium sulphide or sodium or magnesium sulphydrate in presence of an ammonium salt, to convert the nitrocellulose into cellulose. The materials may be treated simply by soaking or by passing them continuously through baths. In the case of artificial filaments or threads, the treatment mav be carried out continuously with the production of the materials by the dry or wet methods. When a solution of nitrocellulose in a volatile solvent is employed for the continuous impregnation, the threads or the like may be passed through an evaporative chamber instead of a coagulation bath in order to fix the nitrocellulose thereon. In examples, a cellulose acetate film is immersed in a bath composed of a saturated solution of cellulose in an aqueous solution of zinc chloride and thereafter washed with dilute hydrochloric acid and water; a cellulose acetate warp is run slowly from a beam through a bath containing a solution of viscose. combs, reeds or the like being provided at each end of the bath to prevent contact between adjacent threads, and then into a precipitation bath comprising for example a solution of sodium bisulphate and the threads are wound on a perforated warp beam, whereon they are washed with water until free from salts and sulphuric acid and then dried ; cellulose acetate silk is impregnated with cellulose by applying a solution of nitrocellulose continuously with the dry spinning of the artificial silk and then denitrating. Specification 295,582. [Class 15 (ii), Dyeing, Processes &c. for], is referred to.
